Chilling photos of slain Brooklyn cop Peter Figoski’s blood-stained shield and uniform were revealed in the first-degree murder trial of his killer today – bringing tears to the hero cop’s mom as she watched from the courtroom gallery.

Career criminal Lamont Pride, 28, shot Figoski once in the face when the decorated cop and father-of-four responded to a call at the East New York apartment where Pride and four other thugs were robbing a drug dealer.

Pride remained motionless as his deadly handiwork was projected onto courtroom screens.

The crime scene photos showed how Figoski’s blood soaked his bulletproof vest and uniform and spattered his shield after the December 2011 shooting.

While the slain cop’s mother became emotional over the gruesome photos, all four of his daughters stayed away from Brooklyn Supreme Court for the first time since the trial opened last month.

“When I opened the door, I saw the police officer laying on the floor with his legs up in the air,” testified Carlos Feliciano, 52, owner of the building where Figoski was gunned down.

“Was he moving?” asked assistant district attorney Howard Jackson.

“No,” Feliciano answered.

Prosecutors have said that Feliciano’s nephew, Nelson Morales, 28, picked out the drug dealer who rented his uncle’s ratty basement apartment as an easy stick-up target.

Feliciano said he called the cops after the violence downstairs woke him up.

He added that when cops arrived he pointed them downstairs and told them to be careful.

After the shooting Feliciano’s nephew Morales and another crook even pretended they weren’t robbers and were trying to help the beat-up dealer.

“I asked him what the hell you doing down there? He was the last person in the world I expected to see down there,” Feliciano testified he said when investigators brought his nephew into his apartment.

In other testimony, a NYPD detective said he caught getaway driver Michael Velez by tracking his cell phone to a Bushwick apartment.

Pride has admitted he shot Figoski but claims the gun went off accidentally as he tried to escape. He faces life in prison without parole.

Getaway driver Velez, Pride’s co-defendant, faces second-degree murder charges in the same trial – and could get 25 years to life.

Morales and fellow thug Kevin Santos, 31, will face trial later this year. Another robber, Ariel Tejada, 23, flipped on the other crooks and is expected to testify tomorrow in exchange for an 18-year-sentence.
